Align Probiotics have high product purity but very low label accuracy and projected efficacy, according to LabDoor. The product ranks the lowest in value and 25th out of 30 in quality by the research group.
In LabDoor's study, 21 of the 30 products inaccurately reported the amount of viable bacteria by 50 percent. Yeast and other bacteria contaminated some, while still more revealed a 2,000 percent label variance.
The study ranks Renew Life Ultimate Flora Critical Care as the highest quality probiotic supplement and Nutrition Now PB8 as the highest value pro-biotic supplement of those included in the test, reports LabDoor.
